Hannah Gray was a laundress and seamstress who used part of her income to promote the anti-slavery movement and support her church. Through her will, Gray donated her house at 158 Dixwell Avenue (no longer standing) to be used as a refuge for "indigent colored females." Because her will did not include funding to administer the house, it was almost sold for delinquent taxes in 1904. It was saved by the Women's Twentieth Century Club, an organization of African American women that took responsibility for maintaining it. The present Hannah Gray House at 235 Dixwell Avenue, acquired in 1911 and accommodating more residents than the original structure, continues in operation in accordance with its founder's goals. The building is included in the Winchester Repeating Arms Company National Register Historic District. It is privately owned and not open to the public.
